Less than a week ago I found that one of the batteries leaked and it had all gunk in the battery compartment. I cleaned it, then replaced the batteries. Once I put the batteries in, the TI turned on but it when i press any buttons, it doesn't respond. I tried resetting it, but it still doesn't work. How can I get this thing to work?

Re: My TI-89 won't respond to any buttons
I don't know how you went about cleaning the battery contacts but if there was any chance to have gotten moisture into the case, it may never work again.
The circuits operate with currents in the nano & femtoampere range and even a breath of moisture can temporarily disable them because of stray currents.
The failed battery may have also damaged fine printed circuit traces as well.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and hold the diamond key. Press and hold the + key for a few seconds and see whether the screen becomes legible.
If this doesn't do it, please respond to this post and we can go on from there.
Take out one battery. While holding the "On" button, put the battery back in. I can honestly not explain what happened, but it has happened to me multiple times as well. You might have to do this more than once, but within a few attempts, it should start working again. Tell me how it works out, and hope this helps!
I have a regular TI-89 (HW2)...have had it for 6 or 7 years. Suddenly it's doing the same thing. I have to put new batteries in it every week or so. I even replaced the backup Li-Ion battery. I'm getting really tired of buying new batteries but don't want to go shell out 100+ for a new one.
Anyone have anything on this? I'm having trouble finding much on this...
If you download games and some third party software can be running all the time draining your batteries. Some of the APPS with Ti 84 will do the same thing. I'd try and find the problem software and delete it.
Well, not a long time ago I have had a similar trouble regarding to my Texas Instruments Calculator Voyage 200. It was forzen too doing some calculus. Also, one friend had a similar problem regarding to the fozen calculator...
I fixed it by reading in the manual that it can be reset!!!...There is a combination of keys that you can press to reset the calculator...this obligates the calculator to load the OS from the EPROM memory where is this basic sofware!!!... If I do not remember wrong the keys are: 2nd + Lock + on/off keys!!! But try to look for the manual and in some part of it is those key combination!!! Good Luck!
